  1. Our Objective : An Ideal Situation of the Summation Calculation of the FP Decay Heat

  2. Summation Calculation of FP Decay Heat λi Eiβ Ni Pβ（ｔ） = ∑ (β-rayComponent) Pγ（ｔ） = ∑ λi Ni Eiγ (γ-rayComponent) λi : Decay Constant Eiβ, Eiγ : Average β- and γ-ray energy per decay

  3. Early Stage of the FPDD File Development In the end of 1970’s : JNDC(JENDL), UKPFDD,ENDF-B

  4. Improvement Achieved by Introduction of Beta-decay Theory JENDL, ENDF/B-V,-VI Gross Theory of Beta-decay U235, Beta U235, Gamma

  5. JEFF3.1 may be a good basis for introduction of the future TAGS data
